Creamy Baked Chicken Alfredo Stuffed Shells
Chicken Alfredo Stuffed Shells are exactly what they sound like: jumbo pasta shells filled with a seasoned chicken and ricotta mixture, then baked in garlicky Alfredo sauce under a blanket of melted mozzarella.

It is the kind of dinner that feels like a weekend project but comes together on a busy Tuesday, especially if you grab a rotisserie chicken.
Why These Stuffed Shells Are a Weeknight Hero
The filling is a simple mix of shredded chicken, creamy ricotta, and both mozzarella and Parmesan, so every bite is rich without being heavy. A quick homemade Alfredo sauce wraps everything in a garlicky, velvety layer that feels far more special than jarred sauce ever could.
Even better, the recipe forgives almost every substitution. Swap the chicken for leftover turkey, use cottage cheese if that is what you have, or pour over a good store-bought Alfredo when time is tighter. The dish stays comforting and reliable no matter how you tweak it.
Ingredients

- 20 jumbo pasta shells: from a 12 oz box, cooked al dente
- 2 cups cooked shredded chicken: rotisserie chicken saves time
- 1 cup whole milk ricotta cheese: full-fat gives the best texture
- 1 cup shredded low-moisture mozzarella, divided: part for the filling, part for the top
- 1/2 cup freshly grated Parmesan cheese: plus extra for serving
- 1 large egg: helps bind the filling
- 2 cloves garlic, minced: or 1 tsp garlic powder
- 1/2 tsp Italian seasoning
- 1/4 tsp salt
- 1/4 tsp black pepper
- 3 tbsp unsalted butter
- 3 cloves garlic, minced: for the sauce
- 1 1/2 cups heavy cream
- 1 cup freshly grated Parmesan cheese: for the sauce
- 1/4 tsp salt: for the sauce, plus more to taste
- Pinch of black pepper: for the sauce
- Optional garnish: chopped fresh parsley or red pepper flakes
Variations / Substitutions
- Swap the protein: Cooked Italian sausage, shredded turkey, or even canned white beans for a meatless option all work well here.
- Use jarred Alfredo: You need about 2 cups. Warm it with a minced garlic clove and an extra handful of Parmesan to freshen the flavor.
- Trade the ricotta: Small-curd cottage cheese (drained) makes a slightly tangier, lighter filling. Whole milk ricotta is still the classic pick.
- Add spinach: Fold 1 cup of thawed, squeezed frozen spinach into the filling for color and a vegetable boost.
- Spice it up: A pinch of crushed red pepper flakes in the sauce or filling gives the dish a gentle warmth.

How to Make Creamy Baked Chicken Alfredo Stuffed Shells
Step 1: Cook the Jumbo Shells

Preheat your oven to 375°F (190°C) and bring a large pot of salted water to a boil. Add the 20 jumbo shells and cook them 1 minute less than the package says for al dente, about 9 minutes total. You want them firm enough to hold their shape during baking.
Drain the shells and rinse them briefly with cool water so they do not stick together. Spread them out on a baking sheet while you work on the rest of the dish.
Step 2: Make the Alfredo Sauce

Melt the 3 tablespoons of butter in a medium saucepan over medium heat. Stir in the 3 minced garlic cloves and cook for about 30 seconds, just until fragrant. Pour in the 1 1/2 cups heavy cream and bring the mixture to a gentle simmer. Let it bubble softly for 2 to 3 minutes, stirring now and then, until it thickens enough to coat the back of a spoon.
Take the pan off the heat and whisk in the 1 cup of grated Parmesan, 1/4 teaspoon salt, and a pinch of black pepper. The sauce will look loose at first but will continue to thicken as it cools. Taste and add a little more salt if needed, then set it aside.
Step 3: Mix the Chicken Filling

In a large bowl, combine the 2 cups of shredded chicken, 1 cup of ricotta, 1/2 cup of the shredded mozzarella (reserve the other half for the topping), 1/2 cup of Parmesan, 1 large egg, 2 cloves minced garlic, 1/2 teaspoon Italian seasoning, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Stir everything together with a wooden spoon until the mixture looks evenly blended, about 2 minutes. The filling should be moist and hold together when you press it with your fingers.
Step 4: Stuff the Shells

Use a small spoon to fill each cooked shell with roughly 2 tablespoons of the chicken mixture. Pack the filling in gently but do not overstuff, or the shells may split. You will have exactly enough for all 20 shells, and the process takes about 5 minutes once you get into a rhythm.
Lay the stuffed shells in a single layer on a plate or tray as you work so they are ready to arrange in the baking dish.
Step 5: Assemble the Dish

Spread 1/2 cup of the Alfredo sauce across the bottom of a 9×13-inch baking dish. Arrange the stuffed shells in the dish in a single layer, opening side up. Pour the remaining sauce evenly over the top, making sure every shell gets coated. Sprinkle the reserved 1/2 cup of shredded mozzarella over everything.
Bake the dish, uncovered, for 25 minutes. The sauce should be bubbling around the edges and the cheese on top will be melted and starting to turn pale gold in spots.
Step 6: Broil and Serve

Switch the oven to broil and let the cheese get bubbly and golden brown in spots, about 3 to 4 minutes. Watch closely so it does not burn. Remove the dish from the oven and let it sit for 5 minutes so the sauce settles. Scoop the shells onto plates, spooning any extra Alfredo from the pan over the top.
A Few Notes Before You Start
- Cook the shells short of al dente. They soften further in the oven, and overcooked shells tear easily when you try to fill them.
- Grate your own Parmesan. Pre-shredded cheese often has anti-caking agents that stop it from melting into a silky sauce.
- Rotisserie chicken is a smart shortcut, but if you roast your own, season it simply with salt and pepper so the filling does not end up competing with itself.
- Make it ahead when you can. Assemble the dish up to 24 hours in advance, cover and refrigerate, then add 10 minutes to the baking time. The extra hands-off night is a gift to your future self.

| Servings | Shells | Chicken | Ricotta | Mozzarella (filling) | Alfredo Sauce |
|---|---|---|---|---|---|
| 6 | 20 | 2 cups | 1 cup | 1/2 cup | 1 1/2 cups |
| 12 | 40 | 4 cups | 2 cups | 1 cup | 3 cups |
Storing Leftovers
- Refrigerate: Store leftover shells in an airtight container for up to 4 days. The sauce may absorb into the pasta, but the flavor gets even richer.
- Reheating: Warm individual servings in the microwave, or cover the whole dish with foil and reheat at 350°F (175°C) for 15 to 20 minutes. Add a splash of milk or cream if the sauce needs loosening.
What to Serve With Creamy Baked Chicken Alfredo Stuffed Shells
A crisp green salad with a sharp lemon vinaigrette cuts straight through the richness of the Alfredo sauce. For something even simpler, a pile of roasted broccoli or asparagus with a squeeze of lemon does the same job while staying on the healthy side. If you are feeding a small army, a side of garlic bread never hurts.
Frequently Asked Questions
Can I freeze stuffed shells?
Yes. Assemble the dish completely but do not bake it. Wrap it well and freeze for up to 2 months. Bake from frozen, covered with foil, at 375°F (190°C) for about 50 minutes, then uncover for the last 10 minutes.
Why is my Alfredo sauce grainy?
Grainy sauce usually means the heat was too high when you added the Parmesan. Take the pan off the heat, whisk in the cheese off the burner, and the sauce will stay smooth.
Do I have to boil the shells first?
Yes, jumbo shells must be boiled before stuffing. There is no reliable no-boil method for this dish because the shells need to be pliable to fill, and the sauce alone does not provide enough moisture to cook them through in the oven.
Can I use cooked chicken breast instead of rotisserie?
Absolutely. Season 2 large chicken breasts with salt, pepper, and a little garlic powder, then pan-sear or bake until just cooked through (165°F (74°C) internal). Shred and use as directed.
